Searching options never rewrites selected criteria · case 01

Searching options never rewrites selected criteria is violated by the widget projection.

Verified by executionVariant 1 · 10 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The selected-preserve decision uses `[x for x in d['selected'] if d['query'].casefold() in x.casefold()]` instead of the stipulated facet-search projection.

THE FAILURE

The selected-preserve decision uses `[x for x in d['selected'] if d['query'].casefold() in x.casefold()]` instead of the stipulated facet-search projection.

Unsuccessful approach: The attempted correction `[x for x in d['options'] if d['query'].casefold() in x.casefold()]` still violates the explicit contract fixtures.

Case contract

Searching inside a facet section affects visible options only; selected hidden choices remain part of the filter and empty query restores the full option list. This example checks: Searching options never rewrites selected criteria.

Why this case matters

Filter-widget state and serialization must preserve user constraints while the view changes.

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 10 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

Verification & scope

Deterministic bounded UI-state model only; no browser, query engine, network, or production-standard conformance is claimed. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.

Observations recorded using Python 3.12.14 at 2026-09-29T14:41:02.329642+00:00.
